In the SolidWorks environment, a kind of series connection robot with five degrees of freedom was designed to fit for automatic stamping production line, and a detailed process description of the loading and unloading of robot was presented. At the same time, the theoretical analysis of the above moving was carried out by mathematical model, two kinds of robot coordinate system was established by the D-H method. Then, the kinematic parameters, joint variables and homogeneous transformation matrix were listed. Finally, the positive and negative solutions of the kinematics equation were solved to compare with the actual motion of robot in the actual production. Furthermore, a topology optimization of the base was carried out by ANSYS Workbench, and the quality of base was reduced by 32.6% under the requirements of stiffness and strength. Thus, the optimization effect was significant. Next, the topology optimization results were optimized with the multi-objective parameters to reduce the equivalent stress value of the base as much as possible under the premise of meeting the requirements, and the optimization effect was better.
